The Power of Cohorts

Cohort studies have informed our understanding of cancer from basic biology to prevention and screening

DCEG studies the role of environmental and host factors in the development of a wide range of common and rare cancer types. Descriptive epidemiology utilizes large-scale databases to monitor exposures and cancers to identify areas of public health concern, while analytical epidemiology conducts in-depth investigations of established and novel risk factors for cancer. DCEG is committed to establishing and maintaining a wide range of resources, including study populations with rich data and biospecimen resources to address etiological questions.

DCEG also prioritizes distinct studies in understudied or special populations (e.g. highly exposed populations due to occupation, underrepresented minorities, geographical location, or accidents), and well-powered studies that leverage existing resources.

Following are examples of DCEG cohort studies:

General population cohorts

Alpha-Tocopheral Beta-Carotene Cancer Prevention (ATBC) Study
Connect for Cancer Prevention Study
NIH-AARP Diet and Health Study
Prostate, Lung, Colon, and Ovarian (PLCO) Cancer Study

Connect for Cancer Prevention Study

The Connect study is a prospective cohort designed to further investigate etiology of cancer, outcomes.
